I'm thinking this summer... I'll probably try to just chill.
Read a lot... swim a lot... nap a lot... make out a lot...
Maybe not get a lot of games done.
Yeah man, just take it easy. All of us looking forward to something more in the future obviously have a vested and biased interest, but seriously, personal time comes first. Doesn't matter whether it's game development or something else, them brain meats overheat if you're not too careful.
As someone who appreciates both Aquaria and what glimpses of your personal vision you've let slip on these forums, I highly encourage you to just distance yourself from all this stuff and get in tune with your muse. Run with it, wherever it leads you, even if it means we won't see a sequel for awhile...or ever. I've rather see what you have to offer when you can get into it, and not something that you have to force out of yourself.
